According to the state fire marshal's office, 29-year-old Adam Finnegan of Brewster was arrested Friday night and will be charged with one count of burning a building.

Earlier Friday, a spokeswoman for the state fire marshal's office said the blaze at the Cape Cod Bible Alliance Church in Brewster, which broke out around 3 a.m., was intentional and that an accelerant was used. There were no injuries.

“Whenever there is a fire in a house of worship, it has a tremendous impact on the fabric of a community,” said State Fire Marshal Stephen Coan. “I applaud the investigative team for working methodically and as quickly as possible to arrest the person they believe is responsible for this crime.”

Officials said there's no indication the fire is connected to other arsons investigated in southeastern Massachusetts.

When asked about the incident on Saturday, Finnegan’s father told NewsCenter 5’s Amalia Barreda that the family was “really devastated” and issued a written statement.

"Our thoughts and prayers go out to the congregation of the Cape Cod Bible Alliance Church. To have their church burned down, especially during this holiday season, is heartbreaking. We were as shocked as the community to learn our son may have done this,” the statement read.

It went on to read that Finnegan is mentally ill and has been in and out of psychiatric care.

“It saddens us greatly that the mental health system in this country is so broken," the statement continued.

The 320-member church is affiliated with the Christian and Missionary Alliance. Its members travel internationally to set up churches and help the needy.

Myron Heckman, pastor since 1978, said the building was renovated in 1997. He said it "holds a lot of memories" but is just a building.

Finnegan is scheduled to be arraigned Monday.

In the meantime, parishioners will use the nearby Stony Brook Elementary School for its Sunday services.
